Nice build

..following.
Even i am going with the same Cade model for my new build which would be around March 2022, once the house interior work is done
Most of the equipments are sorted/ordered. I am opting for the brands those have distributors in my country. We do not have a huge range like the US or the Europe, but still decent stuff we get. So just trying to do my bit in supporting the distributors.
Cade S21500 already sitting in the warehouse. Much earlier than expected

.
For the refugium, i am still doing my study and not sure what to do /where to put.
Unfortunately, the section specified by Cade is not very practical in terms of the space and future maintenance .
Removing the baffle and dedicating the entire section for refugium means looking for options for skimmer.
For now i can think of two options:
1. Have a cheato reactor (Tunze mar 3182), will give a clean sump but an expensive option.
2. Put a teeth etched glass/acrylic pane perpendicular to the black baffle after giving enough space for the skimmer placement/removal /maintenance.
This mean theoretically half the water from the overflow will go thru the refugium and skimmer and some directly into the skimmer and move ahead.
3. Remove the baffle and use the same concept as in option #2 but now perpendicular to the socks holder glass pane.
With option #2 or #3, will there be any problems with total turn over thru the sump? or some other issues which i cannot foresee?
Attaching a picture of the sump for a quick view
Suggestions/inputs will be appreciated.
Thanks.
